Page 46: Converting Multi-Channel Audio Sources To Binaural And Transaural Audio Sources
Chapter 5 Feature Introduction 5.3 Converting Multi-Channel Audio Sources to Binaural and Transaural Audio Sources 5.3.1 Binaural Conversion Binaural audio refers to the mechanism of perceiving three-dimensional sound using a two-channel audio source, such as headphones or earphones. When we naturally distinguish the position of sound, we unconsciously recognize the information related to reflections and changes in frequency characteristics caused by the shape of our heads and ears. -
Page 47: Transaural Conversion
Chapter 5 Feature Introduction 5.3.2 Transaural Conversion Transaural technology applies binaural techniques to speakers. For example, techniques that reproduce three-dimensional sound using a soundbar fall under transaural technology. When playing audio through two speakers, typically labeled as L (left) and R (right), the sound emitted from the L speaker reaches not only the left ear but also wraps around the head and reaches the right ear. -
